Thanks JD but surely there must be more to it than weight difference as they are really only a few pounds any way but if that's it then I cant see the advantage for a street car?

Lighter is better, for the street. Aluminum intakes, heads,wheels, etc. Anything to shave weight,every pound counts.

The other difference is bore sizes.
Not going to get into that right now, hitting the rack. Im sure someone else will chime in.
